Data Enable pin can be tricky. Sometimes it is just a high or low to enable the display, other times it has to be signaled at proper timing. Is this info provided somewhere?
There is an option to activate data enable in the configuration. You need to add it. Also use a scope to make sure you signals are of same polarity as your displayed.
By the way, it would have been much easier for you if you used the display from GHI
Just one more question about this display (or at least I hope it’s just one more question)…
You mentioned an option for dataenabling:

Were you able to get this display working? I’m thinking of using this display as well. I asked a Newhaven engineer and he said to tie DE high (to power).
Looking at the Sharp touch screen that GHI uses I notice that the LCD_EN pin on the EMX is tied to DISP (Display ON/OFF signal) on the screen. I assume that I should tie LCD_EN to the DISP input on the Newhaven display as well.
Is the LCD_ED used only for turning the display on/off? Might this pin be tied to the DE input of the screen? Can someone clarify exactly what this pin does?
